Introduction
This manual shows, how to connect the GNS 5892 Starter Kit to a PC in order to verify GNS 5892
module performance and test supported features.
For technical specification, please refer to the GNS 5892 datasheet.
GNS 5892 is one of the smallest ADS-B receiver modules for 1090MHz “virtual radar” monitoring.
The high dynamic signal processing circuit allows ADS-B data reception from near field to wide
range simultaneously.
The module integrates a sensitive RF front-end, signal processing , a high speed data decoder and
an output uart that can be easily connected to a host processor.
Connected to a PC, all ADS-B data is routed to the miniUSB port. A simple command interface is
used to carry out the necessary settings on the module.
GNS 5892 Starter Kit Features
Onboard USB2UART bridge for PC connection
5V DC input via mini USB
LED “frame indicator”
SMA antenna connector

Notes
1
Because of the high data rate hardware handshake is needed to prevent data overflow. GNS 5892 signals the host with its
CTS signal that he is ready to receive data. GNS 5892 examines the receptivity of the host with RTS. If hardware handshake
is not supported by the host the RTS signal must be activated externally. This can be done by connecting the CTS with the
RTS signal directly.
2
If Jumper2 is set, the USBtoUART interface is reset and the serial port can be accessed directly with the Multi-Pin-Connector.

3.1 Getting started ….
1. Connect the ADS-B antenna to the GNS 5892 StarterKit.
2. Insert the included CD into your CD Rom Drive. Change to \Driver folder.
3. Copy the two files from the \Driver folder to a PC folder of your choice.
4. GNS 5892 StarterKit will be connected to the PC via a virtual COM-Port with USB.
This conversion is performed by an onboard chip.
Do not connect the USB cable now!
First, please install the FTDI VCP (Virtual Com Port) driver by invoking USB-Driver-CDM20600.exe.
A DOS window will open and close again after a few seconds when finished.
5. The VCP USB driver is now ready to use.
6. Connect the Starter Kit to your PC by using the USB- to miniUSB cable. This will power up the
Starter Kit (shown by the blinking green LED fix indicator) and establish the active state.
7. You should see a hint on the right lower corner of your PC screen, that a new hardware has been
found and is ready to use.
